@mingmwang, I don't follow why you think there is a a bug in [this example](https://github.com/apache/arrow-datafusion/pull/5171#issuecomment-1420625925). The query does not specify a top level ordering, so limiting the top or bottom 5 are both fair game from a query perspective. Looking at it from a logical vs. physical plan perspective, I still do not see a problem. Order annotations in logical plan aggregations are local to them, they don't have a bearing on output ordering AFAIK. These annotations specify the frame, but that's where their scope ends. If they had any bearing on output ordering, they would have the same effect at the query level too, but they don't. -- This is an automated message from the Apache Git Service.
